4. Operating Instructions
4.1 General Use
- Ensure the trimmer is charged and the desired head/guard is securely attached.
- Press the power button to turn the device on.
- Hold the trimmer at a slight angle against the skin.
- Move the trimmer slowly and steadily against the direction of hair growth for optimal results.
- Press the power button again to turn the device off after use.
4.2 Trimmer Head Use
Use the trimmer head for initial hair removal or to maintain longer hair lengths. Attach one of the adjustable guards for desired hair length (0.5mm, 3mm, 5mm, 7mm, 9mm, 11mm). Without a guard, the trimmer head provides a close trim.
4.3 Foil Shaving Head Use
For a smooth, close shave, use the foil shaving head directly on the skin without any guards. Ensure the skin is taut and move the foil head gently in straight or circular motions.
4.4 Wet or Dry Shaving
The Smoothie 2.0 is 100% waterproof (IPX7 rated) and can be used on dry skin or in the shower with water or shaving cream/gel. For best results, ensure the skin is clean before use.
